SOURCE: black smoke when reved sharply while in stationary

Diesel?? Black some is unburned fuel, due to poor combustion. Get a compression test, but you may also have a leaky injector.
Gas engine?? Due to too much fuel, too rich. Make sure air filter is clean, Clean up your intake and IAC system. Scan it if it continues.

SOURCE: black smoke come from cylinder when car is started

You either have a fuel injector stuck open ( would need replaced to fix ) or a bad coil pack or spark plug. Check engine light should also be on indicating a problem and a code scan should tell you which cylinder has the problem.

SOURCE: I have a 97 merc cougar xr7 4.6 v8 I had a weird

i've been telling people exhaust leak for their problems all night... and you know what... i think it's an exhaust leak =)

seriously check everything from the block to the manifold and look for anything not connected. If you can smell strong exhaust under the hood as opposed to standing behind the car, or if your air filter get dirty incredibly fast, or if your performance degrades (generally cuz i know cars are touchy and weird) as your foot pushes on the gas (not necessarily higher rpm, but actually burning more gas) particularly when it gets hot, that really might be it.

Hard engine vibration in toyota 2.2 engine at 1,000 rpms or less


run fault codes and look for misfiring cylinder. Vibrations are from engine misfires normally consistent with one cylinder . IT may be spark or HT lead or a faulty injector

White smoke coming from the muffler, loud noise...


One potential cause is too much gas. It may be running "rich". Your car may also be burning a little oil. White smoke is water or antifreeze. If you are loosing coolant from the radiator, it's probably a blown head gasket. If not, it is just condensation in the exhaust pipe that is evaporating as the pipes heat up. If the car is running too rich, the unburned gas will cause black smoke and burning oil smoke will be blue.

Hope helps (remember rated this).

My vitara p reg 2L started smoking on start up, now it is misfiring any ideas where i start, I can't see any spark plugs in the engine-maybe i'm blind or stupid


Many new cars hide most of the engine underneath plastic covers that must be removed to find anything. The smoking problem may or may not be serious, but it's likely that the spark plugs will show black oily deposits on the interior insulators. Cleaning or replacing the plugs will usually make the engine run ok for awhile, but with continued smoking, it will foul the plugs again. If all the plugs are fouled, then look for something like a bad PCV valve that creates crankcase pressure when plugged. Worn out valve seals which allow oil to leak into the cylinders can account for smoking only on start-up. These seals can usually be replaced without pulling the cylinder head. Hope this helps!

Plums of white smoke coming from exhuast when accelerated


Well if you have white smoke when reving up engine then its not smoke its STEAM as you have been lossing coolant by the sound of it (yes) or no,,,,IF yes then you have done a head gasket or something else which
is letting in coolant to the cylinders and when it fires it blowes it out the hot exhaust and causes steam ,, as the only other way to get white smoke could be burning brake fluid/ or kerro.
So does your engine get hot /loosing coolant/missing when running ///any of these will cause your problem.
Let me know how you get on ,, Ron

2005 chevy silverado v8, some hesitation, rough idling, ses light on and sometimes flashes. black smoke when reving the engine.


Black smoke could mean it is running rich, have a scan done, it is probably an engine misfire code and it will tell you which cylinder is misfiring. the last digit is the cylinder, unless it says random missfire, It may be time for a good tune up and don't forget the fuel injection system, Clean out the intake and do an induction cleaning on the injectors.
